Abstract : This report describes the results of the validation effort for the following Ada translator: Host Machine: ROLM MSE/800, Data General MV/4000, MV/6000, MV/8000, and MV/10000; Operating System: AOS/VS-Ada 2.03; Host Disk System: 2 96 megabyte drives; Target Machine: ROLM MSE/800, Data General MV/4000, MV/6000, MV/8000, and MV/10000; Operating System: AOS/VS-Ada 2.03; Language Version; ANSI/MIL-STD-1815A Ada; Translator Version: 4.42; and Validator Version: 1.1 (March 4, 1983). Testing of this translator was conducted by SofTech, Inc. The purpose of this report is to document the results of the testing performed on the translator, and in particular, to: identify any language constructs, supported by the translator that do not conform to the Ada standard; identify any unsupported language constructs required by the Ada standard; and describe implementation-dependent behavior allowed by the standard.
